We've seen some crazy façades, but nothing quite like the waterfront pavilion that boasts over 300 mirrored flaps on its façade that makes it look and sound like it's breathing. Appropriately named Breath Box, the pavilion reflects the surrounding landscape and captures the prevailing coastal wind at La Grande Motte in France. Montpellier studio NAS Architecture designed the structure for the Festival des Architecture Vives, which takes place every summer.

The architects used an interesting technique pioneered by Ned Kahn, whose buildings boast kinetic façades made up of tiny flaps that move with the wind and produce gorgeous wave-like motions. They built a cabin with a seaside façade made up of 345 plates of polished steel that reflect the horizon in a distorted way, while from the inside, visitors can see bits and pieces of the landscape, depending on the wind strength.

The cabin itself is built from charred fir that is varnished to achieve the black appearance. The Breath Box was one of seven structures built for the Festival des Architecture Vives in La Grande Motte. The theme of this year’s festival was “sensuality”.
